Biography:

Dr. Idupulapati M. Rao received his BSc degree in 1971 with majors in chemistry, botany and zoology from Andhra University, MSc degree in Botany from Bhopal University in 1973 and PhD degree in Botany (Plant Physiology) in 1978 from S. V. University, in India. He worked for two years as a Plant Physiologist at ICRISAT, Patancheru, India. He moved to USA in 1981 for postdoctoral training at the University of Illinois with Professors Louise Anderson (Plant Biochemistry) and John Boyer (Plant Physiology). In 1984 he moved to the University of California, Berkeley to work with Professor Norman Terry (Plant Nutrition) as an Assistant Specialist.

In 1989, Dr. Rao accepted a Senior Scientist position at CIAT in the Tropical Pastures Program to work on the mechanisms of adaptation of tropical forage species to acid soils and to contribute to the multidisciplinary team working on mechanistic understanding of soil-plant-animal relationships in legume-based tropical pastures. In 1997, he was given the additional responsibility to work with the Bean team on improving abiotic stress tolerance in common bean and the Soils team to overcome soil degradation in the tropics. He worked at CIAT for 27 years and has contributed to the development of abiotic stress (soils and climate)-adapted tropical forage and common bean germplasm options for sustainable intensification of crop-livestock systems in the tropics.

Dr. Rao worked across a wide range of agricultural research areas including plant physiology, plant nutrition, agronomy, plant-soil-livestock-climate interactions, and climate variability and change, mostly related to the sustainable intensification of crop-livestock systems especially for smallholders in marginalized environments. He worked as principal investigator or co-investigator on more than 40 international research projects.  As part of multidisciplinary teams, he has made contributions that impacted on smallholder agriculture through improved food and nutritional security and natural resource management to fulfill United Nations’ recently adopted Sustainable Development Goals (SDGs) to end extreme poverty and tackling the climate change.

Dr. Rao has published 185 journal articles and 61 book chapters. He won the outstanding principal staff award from CIAT in 2000 and outstanding research publication awards in 1999, 2003, 2009 and 2011. He was also part of the CIAT team that won the excellence in science award from the CGIAR for outstanding partnership in 2001.

Dr. Rao is currently working as a visiting scientist at the National Center for Agricultural Utilization Research (NCAUR), United States Department of Agriculture – Agricultural Research Service (USDA-ARS), Peoria, Illinois, USA. Dr. Rao is married to Kusuma and he has two daughters, Madhuri and Subhashini.
